Powder Measure or Scale for hunting loads?

[denton]

Except with unusually fine rifles, at 500 yards and beyond, there is simply no reason to individually weigh charges. It is a waste of time.

Variation does not add linearly, and that makes some counter-intuitive things happen. The variation introduced by switching between common powder measuring methods is practically undetectable, either in accuracy or in pressure.

I ran the math for the 30-06 and for the 223. Because of the special way variation adds, you would have a hard time distinguishing between a lot of ammunition with powder measured on a laboratory scale, accurate to a milligram, and ammunition loaded with a system with 2.5X the variation I have measured in actual loading scales and powder measures.

Here's the other shocker: The Lee Perfect Powder Measure, dispensing ball powder, is at least as consistent as my Hornady scale, which is significantly better than the digital scale I tested.
